US Patent 9552259 Dynamic provisioning of snapshots

A method and system are provided for dynamic provisioning of snapshots in a data backup system with a software defined storage (SDS). The method implemented by the backup system receives a snapshot provisioning request including a user selection of snapshot objectives by a dynamic snapshot module, converts a file system reference mapping to a logical unit number (LUN) of the SDS, consolidates the snapshot provisioning request to the mapping and snapshot frequency, and passes the consolidated snapshot provisioning request to the SDS to provision snapshots.
